How to solve the vortex flow meter problems


Vortex flow meters are mainly used to measure the flow of medium fluids in industrial pipelines, such as gases, liquids, vapors and other media .its characteristics are small pressure loss, large measuring range, and high accuracy .it is almost independent of parameters such as fluid density, pressure ,temperature, and viscosity when measuring volume flow under working conditions. No moving mechanical parts, so it has high reliability and low maintenance .instrument parameters can be stable for a long time .this instrument uses a piezoelectric stress sensor with high reliability and can work in the operation temperature range of -20~250档There are imitation standard signals and digital pulse signal output, which is easy to be used with digital systems such as computers. It is a relatively advance and ideal flow meter.


The main problems of vortex flow meter


The main ones are:. Inaccurate instructions for a long time ;. There is no instruction for a long time ; . The instructions are shaken in a wide range and cannot be read; .the instructions are not returned to zero;. There are no instructions for small flows ;. The change of the indicator cannot keep up when the fluid quality changes; the K factor of the meter cannot be determined, and there are no difference between the materials.
Summarize the main causes of these problems ,and mainly touched on the following aspects:

  1. problems in the selection of the vortex flow meters .some vortex sensors have a larger size in the selection of the caliber or after the design selection due to changes in process conditions. in practice, the smallest caliber should be selected to improve the measurement accuracy. The reason for this is mainly the same Questions ٢ڢ are related. For example ,a vortex street pipeline is designed to be used by several equipment. Due to the sometimes partial use of process equipment, the current practical application flow is reduced. The original application design is too large in size ,which is equivalent to improving the measurable flow. At the lower limit ,the indication cannot be guaranteed when the flow rate of the process pipeline is small, and it can be used when the flow rage is large ,because it is sometimes too difficult to rebuild .changes in process conditions are only temporary .the re-adjustment of the separable parameters indicates the degree of progress.
